Jacob Josefson breaks right collarbone

NEWARK, N.J. -- The sole point earned in the New Jersey Devils' 4-3 shootout defeat against the San Jose Sharks was little consolation considering the loss of center Jacob Josefson, who suffered a broken right clavicle during the first period.

Josefson underwent surgery Saturday morning, according to multiple media reports. He reportedly will be out three to four months.

The Devils now are without their top two centers. First-line center Travis Zajac suffered a torn Achilles tendon during an offseason workout and is expected to be sidelined until December.

"Injuries are tough, but every team has them," coach Pete DeBoer said. "Someone else's misfortune is another's opportunity, but this will certainly test the depth of our organization."

The Devils have called up center Adam Henrique, who had been sent down to the team's AHL affiliate in Albany after the first two games of the season.

Josefson sustained the injury after taking a nasty spill into the end boards with 3:05 left in the first period. The 20-year-old was slow to get up and appeared to favor his right shoulder while skating to the bench before heading off to the trainer's room.

"That really hurt us," Clarkson said of Josefson's loss. "We played OK in the first, but once we lost [Josefson], they started to take it to us."

Josefson, who has one assist this season, suffered a serious injury the last time he faced the Sharks in October 2010. The former first-round pick was forced to undergo surgery for a torn ligament in his right thumb, an injury that caused him to miss almost four months.

The Devils have not yet released an official timetable for Josefson.

Rangers goaltender Martin Biron suffered a similar injury at the trade deadline last February and missed the rest of the season as a result.

"Missing our first two centermen, it's a tough situation," Kovalchuk said, "but this is a chance for other young guys to step up."
